Best fast food breakfast that can be eaten in the car...

Subway does breakfast now too. Steak egg and cheese on an English muffin, toasted with green peppers. Amazing! And actually very nutritionally sound. Even a 6" puts you back under 500 calories. And they do breakfast all day, so I get them for lunch all the time (I’d rather sleep in than eat before work most mornings.)

You are right. I’ve been giving short shrift to Whataburger, ironic, as my late H was an executive with the company. Thanks for putting me back on the path.

Anything to this other than an egg and two pieces of bread?
